AK - Cargo Ship
A cargo ship is a ship that specializes in the task of transporting various cargoes on the water, and is divided into dry cargo ships and liquid cargo ships. A general cargo ship is a type of dry cargo ship. It is a general cargo ship loaded with general packaging, bagging, boxing and drums. The general cargo ship occupies a large proportion in the transport ship. Generally speaking, the 10,000-ton cargo ship means that its cargo capacity is about 10,000 tons or more, and its total load and full-load displacement are much larger.
The general cargo ship mainly carries ships that are packaged, boxed, and bundled with miscellaneous items. Water transport cargo ship is specifically responsible for various tasks cargo ships, there are dry cargo ships and tankers points, cargo ships are dry cargo kind. Generally speaking, the 10,000-ton cargo ship means that its cargo capacity is about 10,000 tons or more, and its total load and full-load displacement are much larger.
Cargo ship ten thousand tons is generally double-decker, 4 to 6 cargo tanks, each cargo tank with a deck cargo hatch, cargo hatches on both sides can be equipped with a 5 to 20-ton crane derrick. Some ships also have heavy-duty booms for lifting heavy cargo, with a lifting capacity of 60-150 tons. The special requirements of the cargo ship is equipped with a huge V-shaped lifting boom, which can lift several hundred tons. In order to improve the loading and unloading efficiency, some cargo ships are equipped with rotary lift cranes.
There is also a multi-purpose dry cargo ship that can carry both general packaged groceries and bulk and container cargo. This kind of cargo ship is more applicable and has higher transportation efficiency than a general general cargo ship that transports a single cargo.
The general cargo ship is widely used, and the total number of tonnages in the world merchant fleet ranks first. The tonnage of cargo ships sailing in inland waters is hundreds of tons and thousands of tons, while the cargo ships in ocean transportation can reach more than 20,000 tons. It is required that the general cargo ship has good economy and safety without having to pursue high speed. General cargo ships usually sail at various ports according to the specific conditions of the goods and the cargo needs, with fixed schedules and routes. The general cargo ship has a strong longitudinal structure. The bottom of the hull is mostly double-layered. The bow and the stern are provided with front and rear tip tanks.
They can be used to store fresh water or load ballast water to adjust the trim of the ship. Prevent seawater from entering the large hold and play a safe role. There are 2 to 3 decks above the hull and several cargo compartments are provided. The hatches are covered with watertight hatches to avoid water ingress. The nacelle is either placed in the middle or at the rear, each with its own advantages and disadvantages. The mid-adjustable hull trim is arranged in the middle and the cargo space is arranged in the rear. There are lifting masts on both sides of the hatch . In order to load and unload large parts, it is usually equipped with heavy-duty booms. In order to improve the good adaptability of the general cargo ship to various cargo transportation, and to carry large cargo, containers, groceries, and certain bulk cargoes, modern new general cargo ships are often designed as multi-purpose vessels.
Generally speaking, the total load capacity of ocean-going general cargo ships is about 10,000~14,000t, some general cargo ships can reach more than 20,000t; the general cargo load of near-ocean cargo ships is about 5,000 tons; the total load capacity of coastal general cargo ships is below 3000t. The number of general cargo ships greater than 10,000 tons in the past 20 years has dropped significantly in both the liner and charter markets, while the number of general cargo ships less than 10,000 tons has remained relatively stable. More than 80% of the global general cargo fleet is less than 10,000 tons. These less than 10,000 tons of general cargo ships generally have a draught of less than 8.5 m. They have low requirements on the navigation channel and good maneuverability. They can easily pass narrow waterways and bridges. Because of the small turning radius required, the water area of the port is low, so it is convenient to enter and exit the small and medium ports.
Because the general cargo ship is loaded with a variety of goods to different ports, self-sufficiency is a feature of the general cargo ship, they all have their own booms, and some have heavy lifting. The requirements for the wharf of the general cargo ship are greatly reduced. Even the polished bar, or even the ordinary rocky coast, can be loaded and unloaded as long as the water depth of the front is sufficient and the sea conditions permit, so the general cargo ship The scope of activities extends to small marinas. Because the cost of a small dock is low, the port fees paid by the ship are low, which in turn lowers the freight cost of the goods. Most of the container ships do not have the lifting equipment. This is mainly because the container ships have a large cargo load. The marine lifting equipment cannot be compared with the specialized container loading and unloading bridges in terms of loading and unloading efficiency or lifting capacity. As a result, the container truck's stay time at the small dock will increase, and the advantage of container transport will be difficult to play.
